15 Claims.

This invention relates to improvements in card punching machines and hasmore particular relation to improvements in punching machines which arecapable of being controlled by another machine located at a distantpoint.

The main object of the present invention is to provide a punchingmachine which is capable of being controlled by a structurally separateand distantly located machine, such as a cash register, with provision0!. means whereby the correctness of the punching on the card can beverifled by its comparison with the entry made in the cash register.

Cash registers are now equipped with one or more totalizers to secure asegregated analysis of the various classification of items enteredtherein. Such types of machines are relatively expensive and to avoidsuch complicated machines it has been the object of many inventions toconstruct such machines with card punching attachments whereby with theaid of existing card sorting and tabulating machines an analysis of thesales may be made in greater detail. Such punching mechanisms wereusually incorporated in the cash register and it is an object of thepresent invention to construct the cash register so that its entry maybe reflected by a card punched in a punching machine located at adistant point, usually in the bookkeeping or auditing department of theplace of business. In this manner, the analysis may take place withoutany interruption to the operator of the cash register necessitated byfrequent withdrawals of the punched cards for purposes of salesanalysis.

With this object of theinvention attained it is possible to locate thecash register at the place of business and by electrical connections tothe punching machine control card punching operations from the cashregister. The punching operations ensue automatically after itsinitiation by the operator of the cash register by the provision of aspecial key.

Obviously, the efliciency of the system is determined mainly by theaccuracy of the punching operation and any discrepancy between the totalamount accumulated in the cash register and by the card tabulatingmachine will usually signify an error in the punching operation. Sucherrors are only discernible by visual inspection of both machines and isusually only found, due to this reason, when a complete series ofentries and card pu'nching operations have been made.

It is, therefore, the object of the present invention to determine theaccuracy'of the punching operation by a comparison of the value of eachcard punched with the amount or value set up on a cash registerimmediately after punching each card. This direct comparison isinstituted after each card punching operation and by suitable signallingdevices the operators of both the punching machine and cash register areinformed when there is an error.

It is more specifically an object of the present invention to provide aseries of mechanisms in the cash register which are diflerentially setto represent the value entered. These mechanisms are then read out tocontrol the punching machine to cause a card to be punched to representthis value.

The card is then analyzed to difierentially set up a series ofmechanisms in the punching machine to represent the value on the punchedcard.

The series of mechanisms of the cash register is then returned to normalunder control of the series of mechanisms in the punching machine, andthereafter the series of mechanisms of the punching machine is returnedto normal under its own control. Suitable testing devices then actautomatically to determine if both series of mechanisms are at normal.Obviously, if the value set up on the cash register is -734- and thecard is punched --'734-- both series of mechanisms will return tonormal. If the card is incorrectly punched to represent 733- the unitsmechanism of the cash register will be ofl. normal and the error will belocated. J

It is a further object of the present invention to cause said testingdevices to selectively assort the cards as to whether they are correctlyor incorrectly punched and to provide suitable locking devices to lockthe cash register when card punching operations are initiated and tounlock it if the card is correstly punched.

The series of mechanisms referred to comprise well known electricalread-out devices controlled by emitters.- The cash register sets upbrush structures of its read-out device and by a controlling emitterelectrical impulses are transmitted by wires of a cable to punchingcontrol magnets at diflerential times to thereby punch by a set ofpunches holes in the columns of an intermittently moving card.

The holes of the card are then analyzed to transmit electrical impulsesto magnets which to diflerentially set up the brush structures of aread-out device of the punching machine. By means of an emitter impulsesare directed at differential but complementary times to control magnetswhich cause the brush structures of the II cash register read-out deviceto return to normal, if the card is punched correctly. The pivoted brushstructures comprise flexible inclined wires and, obviously, they canonly be moved unidirectionally and for this reason both read-out devicesare returned to normal by complementary rotation of their brushes. If abrush structure was at the 7 position only three units of complementarymovement are necessary ,to return it to 0". The brush structures of thepunching read-out device are returned to normal under their own controland another emitter by causing complementary timed impulses to bedirected to control magnets which cause the return of brush structuresof the read-out device of the punching machine to 0. A circuit is thenclosed at one point to determine its continuity by the position of thebrush structures of both readout devices. If one fails to return to 0"the circult is ,opened, a distinctive signal is lighted, the card isrejected and the cash register fails to unlock.

The provision of electrical control instrumentalities in both machineslends itself admirably for distant control and this object is attainedby a novel electrical solution.

The various operations instituted in the punching machine proceedautomatically without attention of either operator. All incorrectoperations are immediately discernible, such as, failure to reset bothread-out devices, whether due to incorrect card punching, mechanical orelectrical failure, the failure of a card to feed in the punchingmachine, etc.

It is a further object of the nivention to provide for punching ofrepetition data on each of a series of cards. punching machine to puncheach card to represent, for example, the clerk operating the machine. Ina similar manner, there is a control in the punching machine torepresent the machine number, for example.

The invention is shown by way of example applied to a well known form ofcash register which is equipped with a value indicating mechanism. If acard is incorrectly punched the indicating mechanism will indicate thevalue that should have been punched since it is not restored to normaluntil at the beginning of the next cash register operation.

Instead of the cash register any other form of entry device may be used,such as, an adding machine, calculating typewriter, etc., and theinvention is not to be limited by the combination herein disclosed.

The cash register shown in connection with the present improvements isfor illustrative purposes only as any other iorm of item entryaccounting device may be employed. The type of machine shown is wellknown and a complete description thereof may be found in numerouspatents, particularly the patent issued to J. P. Cleal and F. A.Reinhard, No. 580,378, dated April 13, 189

As shown in the patent referred to the ma-, chine is provided with aseries of banks of keys, of which only one bank is shown in Fig. 1.These keys are indicated by reference numeral I0 and are depressedagainst the tension of their springs H to determine the differentialmovement of operating segments i 2. The operation of any of these keysill in a bank elevates its detent l3. The segments i2 are all journaledloosely on a main shaft l4 and are provided with slidable looking orlatching plates I 5. The segments l2 carry pivoted pawls it which areadapted to engage and be stopped by the inner end of any depressed keyit.

When the pawl 95 abuts a depressed key the plate i5 is moved to the leftand into one of a series of notches W of a plate 08 thereby locking thesegment ii! in adjusted position.

The main shaft M is arranged to be oscillated at each operation by acrank arm 89 connected through a link 26 to a second crank arm 2!rigidly mounted on an operating shaft 2'2 of the machine. Rigid on shaftit is a series of segments 23 one for each segment it which togetherwith depending projections 24 serve to move the segments 12 in oppositedirections in a well known manner. It will be understood that althoughthis mechanism is shown in connection with only one bank of keys therewill be a segment l2 and a cooperating mechanism for each bank. Thesegments l2 each carry a rack 28 which in the case of the amount keys ofthe banks is adapted to control the setting of an indicator wheel 21 anda totalizer element 28.

The operating handle 29 (Fig. 4) of the cash register is provided with apinion 30 which meshes with a gear 3| which in turn meshes with a gear32. The gear 32 is secured to one end of a transverse shaft 33 andmeshes with a gear 34 secured to the transverse shaft 22.

Upon the rotation of shaft 22 by the crank handle 29 by the gear drivejust described all of the segments I2 which have previously beendifierentiallypositioned will be first rocked counterclockwise by theprojections 24. Upon the return or clockwise movement of the segments 23shoulders 35 formed on the segments 23 will be engaged by the slides Iof the banks in which keys have been depressed, so that the actuators i2carrying the latches or pawls of the banks in which keys are depressedwill also be carried rearwardly distances determined by the values ofthe key depressed.

The actuators l2 are returned to their normal positions at the beginningof each operation of the machine by the extensions 2 1 which engage withthe actuators l2 and thereby carry them to their normal positions.

The operation of the type of cash register shown is briefly explainedherein as it is so well known by those skilled in the art.

It will be understood that after a rack 26 has been returned to normalfrom its previous differential adjustment it is then turned clockwise aclifierential amount to set up value corresponding to the key depressed.This clockwise movement of rack 28 is utilized to set up an item wheelto represent the value entered and a plurality of such units areprovided to take care of a plurality of denominational orders, althougha description of only one order is herein given.

Continuously in mesh with the segment rack a gear 36 (Fig. 1) meshingwith a gear 3'5 loose on a rod 38. Attached to the gear 3? is a gear 39(Fig. 1a) and adjacent the gear 3Q is a gear 40. The gear It is sleevedto a gear ll loy a sleeve 42 loosely surrounding the shaft 38. The gear4! meshes with a gear 43 attached to an index wheel 44. In alignmentwith the adjacent gears 39 and 46 is 'a broad pinion 45, that is; itisof suflicient width to engage with both gears 39 and when shifted to aposition to engage with both gears 39 and 39. This engagement isprovided to communicate the clockwise movement of gear 39 to the gear 40and thus to the index wheel 44 to thereby set up on said wheel 44 avalue corresponding to the key depressed. The means for accomplishingthis function will now be described.

The gears 45, of which there are several, are carried on a rod 46supported by arms 41 attached to a shaft 48. Secured to the shaft 43 isan arm 49 having a link connection 50 to a bell crank 5| to which isconnected a pitman 52. A cam 53 fast on the shaft 22 cooperates with aroller 54 on the side of the pitman 52 to throw the pinions 45 into meshwith the pairs of gears 39, 40 so that the counterclockwise diiferentialmovement of gears 36 will be communicated to the various item wheels 44.After the segments 26 have been given their differential movements thecam 53 will withdraw the broad pinions 45 out of mesh with the pairs ofgears 39, 49 and they will remain so disengaged during thecounterclockwise or restoring movements of the segment racks 26 at thenext operation of the machine.

The above described mechanism is essentially the same as that shown inconnection with the engaging mechanism for the totalizer utilized in themachine disclosed in the aforesaid Clea] and Reinhard Patent No.580,378.

In mesh with the gear 43 is a gear 55 (Fig. 1) which is in mesh with agear 56 to which is secured a brush structure 57 so that the brushstructure 51 is angularly displaced according to the setting of the itemwheel 44. The brush structure carries two brushes, one of which engageswith one of a series of segments 58 and h lized to control the punchingof a card to represent the value of the keys depressed and whichmechanism will now be described with particular reference to Figs. 5 and6.

It should be noted that the register is intended to be used at the placewhere sales in a busimass are made while the punching device is lo catedat a distant place, preferably in the bookkeeping or auditing departmentso that as the various sales are made a card is punched at a distantlylocated place to give unchangeable records of the sales made. Hence, itwill be observed that the punching machine disclosed in Figs. 5 and 6 isstructurally separate from the cash register or other item entrycontrolling device and distantly located, although they are electricallyinterconnected for control operation to be described.

Figs. 7c and To when adjacent in the order they are just mentioneddisclose the preferable form of electrical wiring'diagram. When anamount is to be punched on the card the operator depresses a start keyST mounted on the cash register but only disclosed in the wiring diagramin Fig. To. This completes a circuit, described from the negative lineside til, through contacts ST, a wire magnet to the positive line side65, thus energizing magnet t3 which causes a series of contacts 53a,63b, 53c, and 63d to close.

The circuit for the motor M of the punching device is now completedsince its circuit is from the positive line side 5i, through motor M,contacts 53b, to the negative line side. The circuit for the motor N(Fig. 3) of the cash register is also closed as it leads from thepositive line side ti, through motor N, contacts 632) to the negativeline side 59. Motors M and N now operate.

A stick circuit for magnet $3 to retain its series of contacts 53o, 33c,etc closed is provided by a line wire leading from closed contacts 53ato contacts CC-2 now closed, to the negative line side to, and anotherstick circuit leads from contacts 63a, wire 65, and relay contacts 660closed when magnet 66 is energized, and thence to the negative line side60. The circuit for the energization of magnet 66 will be describedlater.

The blank cards to be punched have been placed in a magazine 61 (Fig. 5)of the punching machine so that the lowermost card rocks a pivhi it willbe evident that this will close the circuit.

of the magnet 69, thereby causing the energization of the same, and theclosure of contacts 69a.

A circuit fora card feed clutch magnet I0 is closed when cam contactsCC-I close and which is described as follows: from the positive lineside 6|, (Fig. 7a) magnet '10, contacts 630 now closed, contacts 69a nowclosed since there is a card in the magazine 61, contacts 661) closednormally by a spring attached to one contact blade, the circuit beingclosedxto the negative line side 60 when contacts CCI are closed by anoperating cam.

From Fig. 6 it will be evident that motor M drives a pulley I2 to whichpulley there is secured a pinion 93 driving a gear I3 to which there issecured a pinion I4 meshing with a gear I5 which is loosely mounted on ashaft I6 but attached to which is another driving gear 11.

Attached to gears I5 and Ti is a notched disk 18 loose on shaft I6.Adjacent the disk "I8 is an arm I9 secured to shaft I6 and carrying aclutch pawl 80 pivoted thereon. The pawl has an extension adapted to fitin the notch of the disk 18 and is urged to engage the disk by a spring8|.

However, the pawl is held disengaged by an armature latch 02 whichengages an extending arm on the pawl. When the card feed clutch magnetis energized the associated armature is attracted and latch 82 is rockedto the left about pivot 83, releasing pawl and connecting shaft 76 tothe driving gears.

The gear 'I'I which it will be observed is continually rotating is inmesh with a gear 84 which is in mesh with a gear 85 secured to a shaft86. The shaft 06 carries a series of cams adapted to close contactsdesignated herein as the CC contacts one of such for instance, being thecontacts CCI. Therefore, these are closed at a .certain point in thecycle to cause energization of the card feed clutch magnet I0.

When shaft i6 is operated a pair of complementary earns 07, 80 (Fig. 9)fast thereto are operated. A two-armed lever 89 secured to a shaft 90carries a pair of rollers cooperating with the cams 81, 86, so as torock the shaft 90. Attached to the shaft 90 are sector arms M (Fig. 5)provided with gear teeth that mesh with racks on the picker slides 92. Aknife 93 attached to the slides is adapted to engage the bottom card inhopper 61 and move the card to the left (Fig. 5) when the picker slides92 are reciprocated by the earns 87, 88 on the shaft 16.

The gear which drives the gear I3 (Fig. 6) and which is attached to thepulley I2 is designated by numeral 93 and the same is attached -to ashaft 94 and rotates continually.

A roller 95 (Fig. 9) on a stud extending from the gear 93 forms a meansfor driving a Geneva step motion gear 96 with an intermittent movement.The Geneva gear 96 is attached to a shaft 91 but is locked in eachposition by the cooperation of a concentric formation 98 at the. end ofeach radial extension with a hub 99' on shaft 94. The roller 95 movesidly for the greater part of the are about shaft 94 until it engages inone of the slots I00 in gear 96. The gear is moved with a graduallyaccelerated and then gradually retarded motion which is stopped as theroller 95 slips out of a slot I00. The gear 96 is released for each stepof movement by a depression IOI in the side of hub 99. The depressionIOI is presented only when the roller 95 is in position to drive thegear '96.

Attached to the shaft 91 is a gear I02 which meshes with a gear I03 anda gear I04. The gear I04 is attached to a shaft I05 to which is secureda pinion I06 (Fig. 6) in mesh with a pinion I01 attached to a shaft I08.As shown in Fig. 5 a pair of rollers I09 is secured to the shafts I05and I08 and thereby the card is fed between the rollers I09 and to aseries of punches H0 in a step-by-step motion. To feed the card as itpasses the series of punches there is provided a pair of rollers III(Fig. 5) attached to shafts H2. Shafts II2 are intergeared by pinionsII3 (Fig. 6) and the uppermost gear H3 is rotatable with the gear I03.

Therefore, the card is fed by the pairs of rollers I09, and III in astep-by-step movement past the line of punches H0, of which there is onefor each column of the card.

Referring to Fig. 5 and the wiring diagram when the card emerges fromthe hopper 61 it operates to close the die card lever contacts DCL (Fig.7a at the right of a horizontal central line) thereby extending thenegative line side 60 to a commutator ring II5 of an emitter shown inFig. 7a and designated Emitter No. 1. It is well known that cam contactsmay be timed by a cam to close at the end of one cycle and continue theclosure for the first part of the next cycle as illustrated for CCI inFig. 10. This same overlap is provided by the cards for card levercontacts DCL and RCL. The first card will close such contacts at the 14point in the cycle, keep the contacts closed during the remaining partof the cycle, and such contacts are also closed during the first part'ofthe next cycle from D. to 14. The larger heavier timing line between Dand 14 indicates this overlap. The above makes it clear that successivecards keep contacts DCL and RCL closed. As shown in Fig. 6 the gear 85meshes with an idler pinion H6 which is in mesh with a gear H'I attachedto the shaft I 98 of the emitter in the punching machine. The brush H9engages the segment H5 and the brush I20 engages one of a series ofsegments PM.

By the gear driving connections shown the segments I2I are caused to beengaged by the brush I 20 in the order that the corresponding indexpoints of the card to be punched are presented to the punches H 0 of thepunching machine. From the segments lZI there are wire connections in acable I22 which lead from the punching machine and as shown in Fig. 7ato electrical devices of the distantly located cash register. If, forexample, the brush structure 57 (Fig. 1) should be positioned torepresent 9 then the card will be perforated at the nine index pointposition to represent 9 by the following electrical connections. At thetime the 9 index point is beneath the punch |I0 brush I20 engages the 9segment I2I, extending the line through a wire in cable I22 to thesegment 589 (Fig. 7b)

which is engaged by its related brush structure 51 and by its commutatorsegment 53 the line is extended to a plug socket I23.

By a plug connection I24 the line extends by a wire I25 to a socket I23,and thence by a plug connection I21 to a punch control magnet I28, whichleads to the positive line side 3|. Only one emitter is necessary for aseries of read-out devices.of the cash register and the banks of keyswhich are to control punching operations are selected by the plugconnections I23. Also punching in the desired card columns can beselected by the plug connections I21. Thus, as the card is stepped alongit is punched in the various colums. Any suitable punching mechanism maybe provided and the following is a description of a preferred form whichis shown in detail in the application of C. D. Lake, Serial No. 685,379,August 9, 1933, now Patent No. 2,032,805, dated March 3, 1936.

After leaving the first set of rollers I33 the card is fed between astripper plate I33 and die plate I3 I. Then the card enters between thepair of feed rollers III which feed it between guide plates I32 of asensing station. A card lever RCL (Fig. 5) is operated as the cardpasses between sensing brushes I33 and a contact roller I34.

The selective operation of the punch plungers II3 will be explained withreference to Figs. 5 and 8. In Fig. 8 it is noted that the continuallyrotating shaft 34 is formed with an eccentric I35 which is encircled byan arm I33. The upper end of this arm is pivotally connected to an armI31 on shaft I33 which is provided with another pair of arms I33.Between these arms I33 and a punch operating bail I43 there is providedan adjustable turnbuckle connection. A threaded rod I is pivoted at I42on arm I33, and another rod I43 is pivoted at I44 on bail I43; both rodsbeing connected by a double ended bolt I 45 which is adjustable to varythe position of the bail I43.

The ball I43 is pivoted on a stud I43 in the main side frames andcarries a punch actuating bar I41 which is adapted to cooperate withnotches I43 (Fig. 5) in any of a plurality of selected interposer pawlsI43. Each of the punch plungers II3 has an interposer pawl I43 which ispivotally connected thereto by a pin I33. Normally the pawl I49 is heldout of the path of the bar I41 (see Fig. 5) and the plunger H3 is heldabove the die by a spring I 5| attached to the pawl; However,

when a magnet I23 is energized, the associated pawl is drawn intocooperation with bar I41 and the related plunger is subsequentlydepressed to perforate the card.

The armature I32 of the punch controlling magnet I23 is part of a leverI33 pivoted at I54. The lower end of lever I33 is pivotally connected toa call wire I55 the other end of which is pivoted at I33 on pawl I43. Aplurality of such connections are made, one to each pawl, the magnetsI23 being arranged in staggered rows and columns. The brackets I31 carrythe ma nets of one row as a unit, and have arms I33 which hold aninsulation bar I33 suspended above the magnets to function as a terminalbar.

When attracted, the armature I32 swings the lever I53 in a clockwisedirection, Fig. 8, and

draws the wire I55 to the left, urging pawl I43 into cooperation withbar I41. The wires I 33 are guided by a slotted plate I33, and the pawlsI43 are aligned by slots in a plate I3I fastened on a supporting barI32, the plate I" also being used to secure one end of springs IN. Theedge of bar I32 cooperates with a cam face I33.;n, each of the pawls I43to hold the selected pawls into cooperation with bar I41 as the bar I41is lowered An extension I34 on a fixed bar I35 cooperates with the upperends of the pawls to cam them in a clbckwise direction out of engagementwith the ascending bar I41 on the return stroke of the bail. In order topositively hold the pawls in disengaged position, the end of bar I41cooperates with a cam face I33 on each pawl. There is a limit to thedownward motion of the plungers I I3 because of the presence of a fixedbar I31 which projects into notches I33 cut in the side of plungers II3. The plungers are guided above the holes in the die I3I by sliding inholes in a fixed bar I39 and the stripper plate I33.

The operation of punching is timed to occur during the pause in cardfeeding when the Geneva wheel 93 (Fig. 9) is not in action. Theeccentric I35 (Fig. 8) is placed on the shaft 34 in such a position thatthe bail I43 is reciprocated while the roller 33 is out of engagementwith wheel 33. As the bail I 43 and bar I41 are reciprocated, any of thepawls may be moved over by the call wires until notches I48 engage theend of bar I 41. Then the connected pawls and plungers are depressed toperforate the card and quickly withdraw therefrom to permit the feedingof the card to continue to the next index position.

Referring to the wiring diagram, it will be recalled that magnet 33 isheld energized by the closure of contacts CC--2, since closure ofcontacts 33a is retained by the continued'depression of the'start keyST, the operating cycle being so short in time that the operator willhold the key ST depressed sometime during the closure of the CC-2contacts. Therefore, since contacts CC-'-I are closed at the start ofthe next operating cycle all necessary operations including theenergization of the card feed magnet 13 will always be effected at adefinite point in the first cycle, although the cams on shaft 33 may nothave been at a normal starting position when key ST was manuallydepressed.

A cycle is herein considered to be a single revolution of the camcarrying shaft 33 (Fig. 6).

After the start of the feeding of a card cam contacts FC-I close. Thesecontacts, as shown in Fig. '6 are closed by a cam secured to the drivenshaft 13 and therefore, as shown in Fig. 7a cause the energization ofthe relay magnet 33 and closure of contacts 330, thereby closing a stickcircuit for relay magnet 33. To cause continued energization of magnet33 there is provided a stick circuit for magnet 33 described as follows:from the positive line side 3 I, magnet 33, relay contacts 335, the leftcontacts 243!) now closed, ejector card lever contacts ECL-I now closed,to the negative line side 33. Therefore, contacts 33a will remain closedas long as the last described stick circuit is held closed. The motors Mand N will continually operate because contacts 33b are held closed bycontinued energization of relay magnet 33.

Attention is directed to the fact that when contacts 33b are opened dueto the energization of relay magnet 33 the circuit for card feed clutchmagnet 13 is opened to prevent repeated energization of this magnet 13even though contacts CC'I close during the next cycle of operation.Hence, only one card will be fed from the hopper 31 (Fig. 5) during thesuccessive cycles of machine operation. The pair of rollers I IIcontinue to rotate so as to feed the card past the analyzing brushesI33. The first cycle of operation in which card feed occurs brings theleading 6 edge ofthe card to the line of punches I I0, while the secondcycle of operation inwhich punching occurs brings the leading edge ofthe card to the analyzing brushes I33, at which position of the card.card lever contacts RCL will be closed.

From Fig. 711 it will be evident that closure of card.

lever contacts RCL during the second cycle of operation will cause relaymagnet I to be enersized which will cause the closure of its contacts"011 and H022.

During the first part of the second cycle of machine operation theaforementioned card lever contacts DCL closed and when contacts CC4close at the end of this cycle a circuit described as follows is closed,from the positive line side 6|, a feeding roller clutch magnet I1I, wireI12, cam contacts CC4, card lever contacts DCL, to the negative lineside 60. Magnet IN is shown in Fig. 6 and is adapted to cause theoperation of supplemental sets of feeding rollers during the third cycleof machine operation, in which the punched card is analyzed.

Referring to Fig. 6 it will be evident that the gear I03 is in mesh witha'gear I12a which is loosely mounted on a shaft I13 but rotatable with anotched disk I14. Secured to the shaft I 13 is an arm I carrying theusual clutch pawl I16.

I To the shaft I13 there is secured a gear I11 (Fig. 9) in mesh with alarger gear I10. While in Fig. 9 it appears that the gear I11 is in meshwith gear I03 it should be noted that gear I03 is in a diiferent planeand is in mesh with the gear I12a, as shown in Fig. 6. The armature ofclutch magnet I1Iv is designated by numeral I1Ia. The operation of thisclutch is similar to the clutch controlled by magnet 10 and a moredetailed description, therefor, need not be given. At the beginning ofthe start of the third machine cycle, the notch in disk I 14 will beengaged by the clutch pawl I16 and gear I18 will then be driven in astep-by-step fashion since it is controlled by the Geneva gear wheel 96.Gear I18 is secured to a shaft I19 and by intermeshing gears I80 drivesa pair of rollers I8I (Fig. 5). A gear I82 (Fig. 6)

in mesh with one of the gears I80 drives one of a Pair of intermeshinggears I83 to drive a pair of feeding rollers I84 (Fig. 5). Meshing withgear I18 (Fig. 6) is a gear I85 in mesh with a gear I86 secured to ashaft I81. Shaft I81 carries a gear I 88 in mesh with a gear I89 todrive a pair of feeding rollers I90 (Fig. 5). Idler gear I9I (Fig. 6)driven by a gear I 88 is in mesh with one of a pair of intermeshinggears I92 to drive the last set of feeding rollers I93 (Fig. 5).

It should be observed that magnet "I is held energized after the firstrevolution of the disk I14 to prevent a disengagement of the clutch pawlI16 from the disk I14 after the first revolution of the disk I14. Thisis done because the gear ratios selected and employed in the machine ofPatent No. 2,032,805 require a second revolution of shaft I13 during themiddle of the third cycle of machine operation so as to feed in thepresent machine the card entirely past the analyzing brushes I33.Referring to the wiring diagram Fig. 7a and Fig. 6; it will be seen thatthe armature of clutch magnet I'II closes contacts 694 when clutchmagnet I18 is energized. During the last part of the second cycle aspreviously stated when contacts CC4 close to energize clutch magnet I1Icontacts ICC-I6 are also closed at this time and the latter are retainedclosed during the middle or the third cycle of machine operation'toretain the 5 energization of magnet I1! during the thirdcycle ofoperation by providing a stick circuit for magnet I1I through contactsI94. By timing contacts CCIG so as to be closed at the completion of thefirst revolution of shaft I13 the continued energization of magnet I1Iwill retain pawl I16 in engagement with the notch of disk I14 and as thepawl I 16 will not be rocked out of engagement with the notch of thedisk a second revolution thereof will be effected. Card lever contactsDCL by virtue of the passage of the card past the related card leverhave .opened and are, of course, open at the end of the third cycle ofoperation so that even though contacts CC4 and CC- -IG close during theend of the third cycle of operation the circuit to magnet I1I will notberclosed' and the card will be stopped between rollers ;I8I v and I84.

During the third cycle of operation the punched card is fed past theanalyzing brushes I33 with a step-by-step motion. Referring to Fig. 7a,and recalling that card lever contacts RCL are closed during the thirdcycle of operation and, therefore, relay magnet I10 is energized toretain contacts I10b closed, contacts I10b extend the negative line side60 by a wire I94a through animpulse distributor ID to a brush I95 incontinuous contact with the metallic contact roller I34.

The series of brushes I33 engage the roller I34 through the cardperforations. Bymeans of plug connections I96 the card columns which areperforated are selected for controloperations-and obviously the columnsselected will correspond to those punched by punches H0; Fromplug'connections I96 there are wire connections I91 connected to relaycontacts I98 which are now closed. The series of relay contacts I98 isconnected to clutch control magnets I99, all of which are wired to thepositive line side 6|. As the perforations are analyzed during thepassage of the card obviously the clutch control magnets I 99- will beenergized at differential times. The magnets I99 are also shown in Fig.5 and, obviously,are a part of the punching machine.

From Fig. 6 it will be observed that the continually rotating gear 84 isin mesh with a gear 200 which is in mesh with a gear 20I secured to ashaft 202. The shaft 202, as will be observed from Fig. 5, drives ashaft 203 by means of a gear 204 secured to shaft 202 which is in meshwith a gear 205 secured to shaft 203. The gear 203 rotates continuallyand in synchronism with the shaft I 13 (Fig. 6) which drives the.feeding rollers which feed the card past the analyzing brushes I33.

The magnets I99 are adapted to set brushes 206 of a read-out device inthe punching machine in a manner by means similar to that shown anddescribed in the aforementioned Patent No. 1,921,454. In general, amagnet I99 is adapted to attract its armature to release a clutchcontrol lever 201 to permit a clutch connection to be effected by aclutch 208. This clutch will connect the shaft 203 with a gear 209 torotate the latter when the magnet I99 is energized.

This rotationwill commence when a perforation is analyzed and terminateat the end of the cycle, thus setting the gear 209 and the brush 206rotatable therewith a diiferential amount. Brush 206 will now engagewith a particular segment 2I0 card are read out and set up on theread-out device shown in Fig. 5.

\ The impulse distributor I. D. referred to and shown in Fig. 7a is ofthe usual construction and comprises a commutator rotating synchronouslywith-the feeding of the card. Wire 181a is connected to a ring of thecommutator which is electrically connected to all the segments, whilethe brush connected to the contacts i'lflb engages the segments at thetimes the analyzing brushes I33 analyze the index-points oi the card.Hence, if there is a perforation at a particular index-point anelectrical impulse will be directed to the appropriatemagnet i99.

During the third cycle of machine operation it will be-recalled cardlever contacts RCL (Fig. 5) closed causing, as stated, the energizationof relay magnet I10 (Fig. 7a) and the closure of relay contacts .i'lfla.When cam contacts CC-S close at the end of this cycle a circuit for arelay magnet 213 will be closed through the relay contacts "a, as shownin Fig. 7a. A stick circuit for relay magnet 2i3 will be effected by theclosure of relay contacts 2 I So closed by relay magnet 2I3, extendingthe circuit from contacts H311 to spring closed contacts 2l4b (Fig. 7b)and thence to the negative line side 60. Contacts 2| 4?) and the relatedrelay magnet 2 are located in the cash register.

When relay magnet 233 is energized contacts 2l3b (Fig. 7a) close. Relaymagnet 2M and a relay magnet 2l5 (Fig. 7b) are each connected to thepositive line side 6i and both are in series with contacts 2l3b (Fig.7a) The circuit for magnets 2H and 2i5 in the punching machine thenextends from contacts M31: in the punching machine through contactsFCC-i in the cash register to the negative line side to thus cause relaymagnets 214 and H to be energized since cam contacts RCC-i are closed atthe beginning of a cycle of machine operation of a read-out device inthe cash register.

Referring now to Fig. 3 it will be evident that motor N, which at thistime is running continually, drives a shaft 31$ through a Worm wheel andgear mechanism 3i? and shaft 316 is adapted to rotate a series of camsfor closing contacts in the cash register designated as, REC-Pl, ECG-2,RCC3 and RCC-J; cam contacts RCC4 being shown in Fig. 3.

Shaft Sid continually revolves and while the magnet 2 it may beenergized at any time during the cycle of operation of shaft tit, camcontacts RCC-l close at the end of one cycle of operation of the shaft3M and are closed at the beginning of the cycle of operation of shai't351% to initiate certain operations in the cash register at a dell--nite time in the first effective cycle. This is analogous to depressionof the start key ST when the contact operating cams of the punchingmachine may be of! normal but causing its operations to start at adefinitely timed starting point in the first cycle.

When relay magnet 2!! is energized, referring to Fig. 7b, relay contacts2H?) will open thereby attempting to open the stick circuit of magnet 2i8 but to prevent this contacts ECU-*3 are shunted across the relaycontacts 2 Nb and they keep the stick circuit of relay magnet H3 closedduring the opening of contacts 2H!) and for a short time thereafter tothus prevent deenergization of relay magnets 2 and 215 by the openingoi! contacts 2l3b.

A stick circuit for relay magnets 2M and 215 is provided by contactsREC-4, which are closed at the time contacts ROG-4 close, and contacts 2Ha which are now closed due to the energization of relay magnet 2. Asstated above the energization of magnet 2 is held over by cam contactsROG-4 and contacts 2H0 are closed "when contacts ROG-2 close.

Due to the above described circuit ior relay magnet 2 contacts 2H0 (Fig.7b) are closed by the energization of relay magnet 2 to perform afunction now to be described. Contacts 214:: are closed by theenergization of relay magnet 2 it and the latter. is held energized bythe cam contacts ECG-2 during the time a brush 2i6 (Fig. 7b) of anemitter designated Emitter #3" in Fig. 7b passes the series of ninesegments 211. The emitter Just described is also shown in' Fig. 3 andthe brush structure thereof is rotated by means of a gear m secured toshaft 315 meshing with a gear 219 secured to a shaft 220 to which thebrush structure 2i is secured. As the brush 216 passes the segments 2!!a series of impulses will be transmitted by lines wires in a cable 22!(Fig. 7a and Fig. 771) connected between the cash register and thepunching unit.

With respect to Fig. 5 it will be recalled that the brushes 206 of theread-out device in the punching machine have been diflerentially set inaccordance with the values punched on the record card, since theanalyzing of the card by brushes i33 determined their diflerentialsetting. The brushes 20B are also shown'in the lower lefthand corner ofFig. la and also the segments 210. The horizontal series of segments 2 iii iorthe same digit is connected in multiple, as explained fully in theaforementioned Patent No. 1,921,454 since a single emitter may be usedto send impulses for a plurality of orders oi? the read-out device.Segments 2M are connected by ten line wires 222 to the segments 2 i! butthe electrical connections are made in an inverse manner. That is forexample, the segment 2479, of the emitter designated "Emitter No. 3 inFig. 7b is connected to all the segments 2W representing the digit "1,segment 2ila to all segments representing the digit 2, etc. Now ii abrush designated 2%: should engage segment 2351, when brush 2|6 engagesthe segment 2 lie an impulse will be directed from the negative lineside 60, (Fig. 7b) contacts 2 Hie, through the emitter, line wire 2221,(Fig. 7a) segment 2W1, brush 2681, to its common segment M2 and thenceby a wire 22 to contacts H51, (Fig. *ibl now closed, to magnet 22% andthence to the positive line side ti. Hence an impulse will be directedat the 9 point in the cycle instead of at point 1 since brush 2M1 waspreviously set to represent the digit 1. In a similar manner, electricalimpulses are directed to magnets 225 at points in the cycle which arecomplementai to the amount represented by the setting or the variousbrushes 2%.

Referring to Fig. 7b a series of contacts 2i51-1c and 25511 are closedby the previous energization oi the relay magnet 2W. Magnets 225 arearranged in the cash register, as shown in i, and they are adapted tocause the rotation of the brushes 5! from their difierentially adiusteolpositions a complemental extent, and if all adjustments were correctlymade, to a normal starting or "0 position; in which case the brushpreviously engaging the segment $39 110? engages the 9 segment 53.

Shaft 318 (Fig. 1) which is continually rotating has attached thereto agear wheel 228 in meshwith a gear 221 secured to a shaft 228. when amagnet 22-5 is energized it is adapted to effect the usual clutchconnection between the shaft 228 and gear 55. When magnet 225 isenergized it releases a clutch lever 229 to engage a clutch 230, oneelement of which is secured to the shaft 228 and the other to the gear55. The clutch device referred to is well known and described in manypatents, and Patent No. 1,307,740 to C. D. Lake, dated June 24, 1919,may be examined for a more complete disclosure. As the gears 55 areturned complementally the brush previously engaging the segment 59should after this operation engage the segment 58 representing Infurther detail, in a, cycle of machine operation when such'a clutch asclutch 230 (Fig. 1) is engaged at the 9 point in the cycle gear 56 wouldbe turned nine steps. Hence, if a brush 206 in the read-out device stoodat a position to represent 1, instead of energizing magnet 225at the 1point in the cycle to turn gear 56 one step, the inverted wireconnections between the emitter 2I6, 2H, 220 and the readout device inthe punching machine comprising line wires 222 of cable 22l would causethe gear 56 to be turned nine steps, in the example just assumed.

It is-further pointed out that the two read-out devices 51 and 206 shownin Figs. 1 and are constructed as disclosed in the patent to G. F. Daly,1,921,454, and they are also similar in construction of certain parts tothe usual Hollerith accumulator shown in Patent No. 1,307,740 exceptthat they do not have the tens carry mechanism shown in the last citedpatent. This permits the resetting of the read-out devices to zero bythe clutches which in Patent No. 1,307,740

are used for entering items in the accumulator iii but in the presentmachine are utilized to re-set the brush carrying elements to zeroposition.

As is shown in the lower part of Fig. 7b the energization of the relaymagnet 2l5 closes contacts 2l511 and these contacts are in series withcam contacts RCC4 which close after the brushes 5! have been reset tozero position, thereby extending the negative line side 60 to a wire 23Iand cause the energization of a relay 232 since the latter is connectedat one side to the wire 23! and at the other side to the positive lineside 6|.

Relay contacts 232a thereupon close, providing a stick circuit for relaymagnet 232 from the positive line side 6| through these contacts andnormally spring closed relay contacts 23% (Fig. 7a) which are connectedto the negative line side 60.

It will be recalled thatthe cam carrying shaft 86 (Fig. 6) of thepunching unit is also rotating and obviously when the 60-6 (Fig. 7a)contacts close by a cam secured to shaft 86 a circuit for relay magnets233 and 234 will be closed, described as follows: The positive "lineside 65, magnets 233 and 234 in multiple,- cam contacts (JO-6, contacts2325 to the negative line side 60. Energization of the magnet 233 openscontacts 233D but the latter are shunted by cam contacts CC-0 which arenow closed and this effectively prevents the deenergization of relaymagnets 233 and 234 by the opening of contacts 232b, which would beperformed if relay magnet 232 was deenergized by opening contacts 2331).

As relay magnet 233 is now energized contacts 233a.- close and since camcontacts 00-! are timed to be closed when cam contacts CC -6 are closed,a stick circuit for relay magnets 233 and 234 will be provided by relaycontacts 233a and cam contacts CC-l but the stick circuit is opened atthe end of the cycle by opening of contacts CC-l.

It should also be observed with reference to Fig. 75 that when contactsRCC-Z opened during the cycle of operation in which and after thebrushes 5'! were returned to normal that relay magnets 2 l4 and 2l5 weredeenergized.

Hence relay contacts 2|51 i1 will now be opened electricallydisconnecting magnets 225 from the read-out device of the punchingmachine shown in the lower left hand corner of Fig. 7a.

The energization of the relay magnet 234 will cause the concurrentclosure of a series of ten relay contacts 2341 to 23410 (see Fig. 7a)and the opening of the series of relay contacts I98. As relay magnet 233is now energized it will also cause the closure of its relay contacts2330 (Fig. 7a) thereby extending the negative line side 60 throughclosed contacts 2330 to a collector segment 236 of an emitter 231provided in the punching unit, which is drivenby the shaft H8 anddesignated as Emitter No. 2 in Fig. 7a. The construction of this emitteris precisely the same as the emitter shown in Fig. 3 and furtherdescription need not be given in view of the detailed descriptionpreviously given for like Emitter #1. The segments 238 of -the emitterare connected to the several seriesof like segments 2|0 of the read-outdevice in an inverse manner, similar to that previously described. Thecomplementary timed electrical impulses will be transmitted by linewires 239 to the clutch control magnets I99 through the closedc0ntacts2341 1o, since contacts 2|51-m (Fig. 7b) are now open. MagnetsI99 (Fig. 5) now receiving the electrical 'iinpulses will cause thebrushes 206 to rotate in the same direction they were turned to securetheir differential adjustment. The series of brushes 206 will now bereset to their normal position. It should be noted that when a brushstructure (of either read-out device) is turned a complemental extentthat one of the brushes engages the zero segment and in each instance itwill comprise the brush which previously engaged the common segmentalcollector, identified by numeral 59 in Fig. 1 or 2l2 in Fig. 5.

Referring to Fig. 7a it will be noted that the energization of relaymagnet 233 has also closed contacts 233d, thus extending the negativeline side to cam contacts CC-l0 which are timed to close after the brushstructures are reset to their normal positions. This extends the circuitto the segment 2l0o which is engaged by a. special brush 206a. It shouldbe explained with reference to Figs. 5 and 7a that rotatable with eachbrush structure 206 is a supplemental brush structure, one beingdesignated 2060. in Fig. 7a. This brush at the normal or reset positionis in engagement with a single segment 2060 and a supplemental collectorsegment 2060. In other words for each denominational order of theread-out device there is a duplication of the structure shown in Fig. 5and shown diagrammatically in Fig. 7a. The segments of the differentorders corresponding to segment 2060 are connected by wire connections240, and in view of the engagement of the brushes, such as 206a, withtheir segments 2060 and zero contact points 2060 the circuit is extendedby a line wire 24l to the zero segment of the read-out device of thecash register shown in Fig. 7b. The read-out device of the cash registeris constructed similarly to that for the punching machine and if thecard was punched to represent the same amount as the item set up on thecash register the circuit will be extended, by similar connectionsdescribed with reference to Fig. 7a, to a wire 242 to cause theenergization of'a relay magnet 243 (Fig. 7a).

It will be understood that following the cycle of operation of theresetting devices for the readout device of the cash register thepunching machine goes through the fourth effective cycle of operation.During this fourth effective cycle of operation the punchingmachineread-out vdevice is reset and during this cycle of operation magnet "I(Fig. 6) is energized to cause the rotation of the feeding rollers IBI,I64, I99 and I93 during the fifth effective cycle of operation by thefollowing electrical control.

When magnet 243 (Fig. 7a) is energized relay contacts 243a are closed,thus providing a stick circuit for relay magnet 243 through the rightcontacts 243b closed when relay magnet 243 is energized, through cardlever contacts ECL2 now closed, to the negative line side. This circuitwill retain magnet 243 continuously energized until card lever contactsECL2 open.

It will be recalled that magnet 66 is still energized and to prevent itsstick circuit through the left contacts 24317 from being opened due tothe energization of magnet 243 which opens the left contacts 24%, camcontacts CC-3 are provided. These are shunted across the left contacts2431; and close a little time before and also when contacts CC-IO close.Thus, the stick circuit for magnet 66 will extend through contacts 66a,cam contacts CC-3, card lever contacts ECLI, to the negative line side.When the right contacts 2432) close the stick circuit for relay magnet66 is transferred to the right contacts 243!) now providing a commonstick circuit for both magnets 66 and 243.

At the beginning of the fourth effective cycle of operation cam contactsCC--1 are closed which retain the energization of the relay 234 and theclosureof contacts 23411 (Fig. 7a). When cam contacts CC9 close acircuit for the clutch control magnet l1l will be completed by theclosure of cam contacts CC--9 and contacts 23411.

'Cam contacts CC--l6 together with the closure of contacts I94 which areclosed by the energization of magnet I" provide the usual stick circuitfor magnet Ill, thus continuing the energization of magnet ill at thebeginning of the fifth effective cycle of operation. At this time thenotch in disk I14 (Fig. 6) will be engaged by the end of the clutch pawlI16 thus causing the feeding rollers l8l, I64, I99 and 493 to rotate.Cam contacts CCI6 retain the energization of magnet l1l during the fifthcycle beyond the middle thereof so that another rotation of shaft I13will ensue, which necessity was previously described.

When cam contacts CCI6 open magnet Ill will be deenergized. However,contacts CC--9 close shortly thereafter and since contacts 2430 are nowclosed (because card lever contacts ECL2 are closed) anotherenergization of mag-- net ill will be effected and its energization willbe continued and extended to and during the sixth effective cycle ofoperation by cam contacts CCI-6.

It will be noted that cam contacts CC1 open near the end of the fourtheffective cycle of operation to cause magnets 233 and 234 to bedeenergized. Of course, this causes relay contacts 23411 to be opened socontacts 2430 are provided to cause the energization of magnet l1! whencam contacts CC-9 close. These contacts 2430 are shunted across contacts23411.

' At the beginning of the fifth cycle of operation the card is betweensets of rollers l6l, I84, (Fig. 5) and at the end of the fifth efiectivecycle the card is between the sets of rollers l93--l84.

At the beginning of the sixth cycle the card is still being fed and bymeans of the rollers I93 the card which has been found to be punchedcorrectly is fed into a receptacle 245. At the beginning of the sixtheffective cycle of operation card lever contacts ECL2 open, thusresulting in the deenergization of magnets 243 and 66.

Since relay magnet 66 is now deenergized stick contacts 660 (Fig. 7a,upper middle) will open to cause deenergization of relay magnet 63.Contacts 63?) will now open to attempt to stop the operation of motor Nof the cash register and motor M of the punching device. It should benoted that cam contacts CC2 are shunted across contacts 660 and theywill hold the energization of relay magnet 63 even though contacts 660open. This will insure a sufficient operation of the motor M so thatfeed rollers I93 will feed the card to allow it to drop in thereceptacle 245. It should be noted that when contacts 6311 (Fig. 711)closed due to the energization of relay magnet 63 caused by thedepression of the start key ST that by a wire 246 a circuit for alooking magnet 241 (Fig. 7b) was closed. Magnet 241 is shown in Fig. 4and when energized it operates a lever 248 to bring a notch 249 thereofinto locking cooperation with a square stud 250 attached to the gear 3|.This will prevent any operation of the cash register during theoperation of the punching machine and in view of the holding of contacts63d closed during the six cycles of operation the magnet 241 will retainthe locking lever 246 in a locking position during this time. Whencontacts 63d open the operating handle 29 (Fig. 4) will be unlocked sothat another item entry operation may be instituted.

The last described operation assumes that the card was punched correctlyand corresponded in each column punched with the value of the itementered by the various banks of keys of the cash register. If the cardis punched to represent the incorrect amount, this amount will,nevertheless, be set up on the read-out device of the punching machineand will subsequently be reset. The true amount which was to be punchedon the card was, however, set up on the read-out device of the cashregister and as this read-out device is reset under control of theincorrectly set read-out device of the punching machine, one or anotherof the brush structures 51 will fail to return to normal position.Hence, the circuit to the relay magnet 243 will not be energized whencontacts CCI close at the end of the resetting of the read-out device ofthe punching machine. Under certain other conditions, relay magnet 243will also fail to be energized when contacts CC-lll close. For example,the amount entered in the cash register may be correctly represented byperforations on the card but due to some mechanical or electricalfailure one or another of the brush structures 291 of the read-outdevice of the punching machine (see Fig. will not be turned to normal.Again; the brush structures 51 (Fig. 1) of the read-out device of thecash register may not return to normal due to some mechanical orelectrical failure, even though the read-out device of the punchingmachine was correctly set to represent the amount entered on the cashregister.

It is desirable that the operator be apprised of any of the abovedescribed faulty operations, or others, since the correctness ofsubsequent card punching operations is entirely dependent upon whetheror not the read-out devices of the punching machine and cash registerare at normal at the beginning of an item entry operation of the cashregister. There will now be described the means whereby incorrectlyunched cards'will be selectively disposed in a reject pocket designatedby numeral 25! in Fig. 5.

As previously stated during the fourth cycle of operation of thepunchingmachine in which the read-out device of the punching machine isreset, contacts CCID close but since the circuit to relay magnet 243(Fig. 7a) is not closed when the brush structures of either read-outdevice are not at normal contacts designated 243d (Fig. 7a) will remainclosed.

However, the energization of the clutch control magnet I'H (Fig. 7a)will be effected by the circuit previously traced and described so thatthe incorrectly punched card will be fed during the fifth effectivecycle of machine operation.

When the card is fed to the left (Fig. 5) by the rollers l8l card levercontacts ECL-l of the left pair (Fig. 7a) will be closed early in thecycle and since at this time contacts designated 243d (Fig. 7a) areclosed, it will be observed that a circuit for a relay magnet 252 willbe closed, said circuit leading from the positive line side 6| throughmagnet 252, contacts 243d now closed, card lever contacts ECL-l of theleft pair now closed to the negative line side 60.

Relay contacts 252a will now close providing a stick circuit for therelay magnet 252 through contacts 252a, stop key contacts SP1 of thepunching machine and stop key contacts SP2 (Fig. 7b) of the cashregister. The energization of magnet 252 will continue until either ofthese stop key contacts are manually opened.

It should be observed that the opening of the right (Fig. '70.) cardlever contacts ECL-l (Fig. 7a) will open the circuit to the magnet 66.This will result in the opening of contacts 660 and the subsequentdeenergization of relay magnet 63 when cam contacts CC-2 open late inthe cycle. The deenergization of the magnet 63 caused by the opening ofcontact CC--2 will permit the opening of contact 6311 and attempt tocause the deenergization of the'locking control magnet '24! (see Fig.7b) to release the cash register for operation. However, under theincorrect conditions now being assumed, it is necessary that the cashregister be locked and it is maintained locked by means of contacts 252d(Fig. 7a) upper right which were closed previous to the opening ofcontacts 6311. When looking magnet 24! (Fig. 7b) was energized, itclosed its contacts 241a. The circuit for the locking magnet 24'' willtherefore now be extended through contacts 241a, maintained by contacts25211, to the positive line side 6|. As previously stated, magnet 252which causes contacts 252d to be closed will be retained energized untileither the stop key of the cash register or the stop key of the punchingmachine is manually depressed. The depression of either stop key willtherefore release the cash register for a subsequent entry operation. i

There will now be described certain operations which take place afterthe resetting of the readout device of the punching machine which, itwill be recalled, occurs during the fourth effective cycle of machineoperation.

Referring to Fig. 'laand understanding that since magnet 243 is not nowenergized due to an incorrect reset operation, it will be noted thatcontacts 243e will remain closed. Whencam contacts CC-H close, camcontacts CC-1 are also closed for retaining magnet 233 energized, sothat contacts 233e are closed. A circuit will therefore be institutedfrom the negative line side 60 (Fig. 7a) through relay contacts 233e nowclosed, relay contacts 243e now closed, cam contacts CCH now closed, toa magnet 256 which is connected to the positive line side 6i. Whenmagnet 256 is energized, it causes the closure of its own contacts 256ato provide a stick circuit through these contacts, contacts 251a, camcontacts CC-IZ to the negative line side 60. Cam contacts 00-! 2 aretimed to be closed at the time contacts CC-'| and CC-l| are closed. Camcontacts CC-l2 will, therefore, continue the energization of magnet 256at the beginning of the fifth effective cycle of machine operation. Atthe beginning of this cycle of operation, card feeding rollers I84 (Fig.5) which engage the leading edge of the card are rotated. When themagnet 256 (see Fig. 6) is energized, it will attract its armature 258to rock a shaft 259 to which the armature is attached. Attached to theshaft 259 as observed in Fig. 5 is a vane or card deflecting plate 260.When the magnet is energized, the free end of the deflector plate 260 iselevated a slight extent and as the incorrectly punched card is nowbeing fed by the rollers I84, it will be observed that the card isguided in the reject pocket 25! during the fifth effective cycle ofmachine operation.

It is desirable that magnet 256 remain energized during this cycle ofoperation and during a portion of the next in order to insure that thecard will be properly fed. The following described circuits adequatelyprovide and insure the desired operation.

During the 'fifth eifective cycle of machine operation, contacts CC-l3close and since contacts CC--l2 are now closed, the negative line side60 will be extended through cam contacts CC-IZ, contacts 251a, contacts256a, through cam contacts CC-l3 to a relay magnet 251. This will causethe opening of contacts 251a and an attempt to open the circuit to relaymagnets 256 and 251. However, at the time contacts CCI3 close, contactsCC|4 are also closed and since contacts CC-|4 are shunted acrosscontacts 251a neither relay magnets 256 nor 251 will be deener'gized.When relay magnet 251 is energized,

relay contacts 251D will be closed thereby extending a circuit from thenegative line side through cam contacts CC-l5 which are closed at-thetime cam contacts 00-" open, a wire 26! relay contacts 251!) now closed,contacts 256a, relay magnet 256 to the positive line side. Obviously,the energization of the deflector control magnet 256 is now undercontrol of the cam con tacts CCI5. Since cam contacts CC|5 are closed atthe time contacts CC-l3 close, relay magnet 251 will be held energizedunder control of cam contacts CCI5. When relay magnet 25! is energized,it will close its contacts 2570, and as said contacts are in series withcam contacts CC-l5 it will be noted that the energization of relaymagnet 25'! will now be continued and placed under control of the camcontacts CC--I5 after cam contacts CC|3 open..

When cam contacts CC-|5 open, relay magnets 256 and 257 will bedeenergized and due to the deenergization of magnet 256, the deflectorplate 266 (Fig. 5) will assume its normal position shown in Fig. 5. bymeans of a spring 262 (Fig. 6)

' attached to the armature 258 of magnet 256.

While the preceding description has described a machine which is fullyoperative for all purposes, there will now be described certain adjunctsin the nature of distinctive signalling devices which indicate to theoperators of the cash register and the punching machine that certainoperations'have been properly completed or improperly carried out.

These various signal devices are illustrated only in the electricalwiring diagram in Figs. 7a and 7b but are attached to the differentmachines. Reference numerals 263 and 26% indicate electrical lamps whichare colored green. The lamp 263 is located at the punching machine forobservance by the operator controlling the punching machine while thelamp 264 is visible to the operator of the cash register since it islocated thereon. The circuit for lamps 261i and 264 start from thepositive line side 6I, through contacts 63d which are closed when relaymagnet 63 is energized, contacts 25212 which are closed when magnet 252is deenergized and then from said contacts 252b to lamps 263 and 264,the other side of each lamp being connected to the negative side. If thepunching operation has been correct and both of the read-out deviceshave been returned to normal, magnet 63 will remain energized and relaymagnet 252 deenergized thereby causing their respective contacts 63d and25217 to be closed.

Therefore, when the start key of the cashregister ST is depressed, lamps263 and 264' will be initially lighted and will remain illuminated untilthe end of the sixth effective cycle of the operation of the punchingmachine when they will be automatically extinguished. The illuminationof the lamps informs both operators that the punching machine is inoperation.

Distinctively colored lamps, designated 265 and 266, in the wiringdiagram indicate to the operators of both machines that some operationhas been incorrectly performed, as has been previously described. Theselamps 265 and 266 are preferably colored red and they are illuminatedduring the operation of the punching machine when an incorrect operationhas been performed. The circuits for both lamps 265 and 266 arecontrolled .by contacts 2520 which are closed when relav magnet 252 isenergized. Such energization, it will be recalled, is instituted wheneither readout device fails to return to normal.

It is desirable that the operators of both machines be informed whenthere is no card in the hopper 61 of the punching machine.

It will be recalled that the card lever contacts MCL (Fig. 5) are closedonly when there is a card in the magazine 61. On the presence of a cardtherein these contacts will close to cause the energization of relaymagnet 69 and the opening of contacts 69b to extinguish a pa r of lamps.These lamps which indicate to the operators by their lighting theabsence of a card in hopper 61 are preferably colored yellow and aredesignated by reference numerals 261 and 268.

One side of each of said lamps is connected to the positive line side 6|and the other sides of each of the lamps are connected to the negativeline side through contacts 6%. Upon the feeding of the last card in themagazine both lamps will be illuminated informing the operators of thiscondition. When cards are replenished in the hopper 61 the lamps willagain be extinguished.

It is, furthermore, desirable to perforate the card in one or morecolumns to designate some fixed data, as for example, the clerkoperating the machine. In the event that the same clerk repeatedlyoperates the same cash register it is desirable that this repetition ofdata be effected automatically without the necessity of repeatedlydepressing the same key.

Referring to Fig. 2, it will be understood from the well knownconstruction of the cash register that when a key is depressed itsdetent segment I3 will be elevated and it will be held elevated by meansof the usual spring urged locking bar 210 which upon depression of a keysprings rearwardly so that its shoulder 2H engages the lower part'of thesegment I3. The machine is provided with a conventional lock 212 andwhen the key 213 thereof is rotated by the clerk retaining the key 213its latch 214 will engage a notch 215 of the raised detent I3. This willretain the de pressed key I6 continually depressed and effect the samesetting of its gear 36 for each machine operation. Obviously, the brushstructure 51 of the corresponding order will be rotated to the sameposition for each cash register operation.

By means of the plug connections I24 (Fig. 7b)

and I2! (Fig. 7a) this order of the read-out mechanism of the cashregister can be plugged to control the energization of one of thepunching control magnets I 26.

This will cause punching in a column to represent the same data, as forexample, the clerk operating the machine, in each of a series of punchedcards.

It is also desirable to designate on each card punched the number of thepunching machine. This will permit identification of the source ofpunching. To this end the punching machine is provided with a read-outmechanism of preferably four orders to set up any digit from 0000-9999.The brush structures 216 (Fig. 5) of each order are manually settable bynotched wheels 21! so that one of the brushes engages a particularsegment 2T8 representing the digit set up. Obviously, the brushstructures 276 remain in the position they are set. The emitterdesignated Emitter No. l in Fig. 7a also has wire connections in a cable219 to the various segments, in the manner previously described, exceptin this case, the segment I2I of the emitter relat ing to a digit isconnected in multiple to the segments 218 relating to the same digit ofthe read-out device now described and so on. In this instance it isdesired to punch to represent the same numbers set up by the wheels 211and the wire connections are not complementarily arranged in this case.By means of plug connections 280 (Fig. 7a) the read-out device may beplugged to control the energization of selected punch control magnetsI28. These will control the punching of fixed data on each of a seriesof cards, representing, for example, the number of the punching machine,a date, etc.
